i am getting problem displaying images in list view. the pages shows only album name not any images.this is my code
<ItemTemplate>
I want to display images that a user uploads in a list view so that all the images a user uploads will appear as at the moment no images appear using the list view but the xml data source file gets updated. I am using VS 2008 usinf asp.net, vb and xml codes. What would I need to do so that the images appaer in the list view.
The code I have used in the aspx page is:
<asp:ListView ID="ListView3" runat="server" DataSourceID="XmlDataSource1">
<LayoutTemplate>
<div id="itemContainer">
<span id="itemPlaceholder" runat="server" visible="true" />

View 2 RepliesI've got a treeview inside an updatepanel. Currently I'm developing on a dev server through a remote connection, when I view the page from the dev server itself, it works. The expand/collapse images display fine. When I view the page from my machine's browser (same url, same browser) it doesn't display the images.
I've added custom images using the CollapseImageUrl/ExpandImageUrl properties, again it works from the server, but not from my machine. The actual rendered html differs. The page also contains some asp:Image controls which work fine in both browsers.
how to display images from a database cant cant seem to find quite what im looking for.
I have a site that allows users to upload their own photos, i would like to be able to display these images, with the discription of the photo underneath or on top of the photo, on the website and allow other users to comment on the photos.
The display can be every photo in the database, later ill impliment a search to narrow it by user later.
Right now I have my database table set up to take the img path, username that uploaded the picture, time it was uploaded, and a description of the photo.
I am working on List View to show Images dynamically. But my image folder is out side my Application folder(means on other drive or in same drive but not included in project ). Now if folder is inside project I know how to give Path , but outside Project it gives me problem in showing images.How to do that.in aspx
<asp:Image ID="ImgPic" runat="server" AlternateText='<%# Eval("CRGIMG_CARGO_IMAGE_PATH") %>'
I am working on one photogallery project, I have admin panel which will let administrators to upload images, save in the file system and name in database. I will retrieve all images in list view and let administrator handle all images which are verticle or horizontal.. I will let administrator to rotate image 90 degree or 360degree in listview edit mode. I have no idea about that.
View 2 RepliesI am trying to find an efficient way of displaying images (about 140x140px) in a webform. We cannot use paging, so we need to display all these images in the same webform.I noticed that facebook (and other sites) lets you display all your images in one page. For a profile qith about 1000 photos, facebook somehow downloads only enough so that the visitor can see images on the screen. Once you scroll, it seems to only download enough so that the visitor can again see something on screen. It works like a good text editor.... instead of displaying a huge file onscreen (like notepad does) and freezing, it only displays enough for the reader to see.
View 2 RepliesI know how to store and retrieve images into the sql database. My question in how do I iterate over the retrieved images to convert to a byte[] array and bind to the image control in the datalist?
View 4 RepliesI'm trying to display images retreived from a sql server table in a GridView.
I found that the approach generally accepted was to have a handler that finally writes the image to the HttpContext.
My problem is that I only get a red X in the image column and not the images I want.
I'm using Northwind database, and I'm displaying data from the Employee table.

I'd like to make a page that displays information from my database, but in an atypical way. Each record from my data includes an image and some information about the image. I'd like to display an array of images, each with its associated data underneath the image. I'm imagining a table with four columns and in each cell there is an image and underneath the image is information about it (name, size, author).
You can get an idea of what i'm trying to achieve by looking at this webpage:

how to implement this with asp.net??
I have a sql database and want to store the image format into the database. I want to then display the image in a gridview. For the database I have entered the location of the image and not sure if this is the right thing to do. I'm not very good at this stuff so could you make it as simple as possible.

I am stuck at this point "Displaying a dropdown list of Categories with a --None -- Option. I want the gridview control to display 2 dropdown list one in read-only mode and the other in edit mode. When a record is in read-only mode, the dropdownlist's enabled property will be set to false."When it's on a read-only mode, it doesn't display the selected Category. it shows but the "No Category". When i click on edit to edit or change category, it doesn't display the selected category.

I'm binding a ListView to a collection of objects which is working fine. Unfortunately when the collection is empty then I'm not getting the text in the EmptyItemTemplate element displayed as I would expect.
Markup code is
[Code]....
When the collection returns a count of zero then the EmptyItemTemplate text doesn't display. I have viewed the page source and it isn't rendered at all (rather than being hidden). I have replaced the DataSource object just with null i.e.
lvListView.DataSource = null
Just to test it and it still doesn't work. No text rendered again.
I have had this problem on other pages I have worked on (and given up and done kludge work arounds) so it's obviously just something that I am missing - doing incorrectly.
I am using mobile list control inside that i inserted a label when i bind any dataset to that list it is not displaying any information. In msdn it is mentioned the mobile list control is equivalent of web control is datalist. The code as follows.
<mobile:List Runat="server" ID="List2">
<Item>
<mobile:Label runat="server" id="lblStudentName" Text='<% #Eval("StudentName") %>'>
</mobile:Label>
</Item>
</mobile:List>
in code behind
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
MTestDataContext dc = new MTestDataContext();
List2.DataSource = dc.Students;
List2.DataBind();
}
}

I have two listviews. The inner listview (InnerListView1) is in the SelecttItemTemplate of the outer listview (OuterListView1). Both listviews are bind in the code behind. The outer listview displays correctly in the ItemTemplate. Neither Listview Listview displays in the SelectItemTemplate. Both should display when I click the Select button. I just get a postback (flicker). The display should include the selected record of the outer listview and the inner listview.
Shown be low are code snipets of the.
Markup:
<asp:ListView ID="OuterListView1" DataKeyNames="entryid" runat="server" EnableViewState="False" EnableModelValidation="True" InsertItemPosition="LastItem" OnItemDataBound="OuterListView1_ItemDataBound" OnSelectedIndexChanging="OuterListView1_OnSelectedIndexChanging"

View 3 Replies I have developed my application using ASP.NET with Visual Basic. I have a table that contains 3 fields. The name of the table is "Customer" and the names of the fields are "Name", "Address", and "Amount". I have a gridview that displays these three columns. I want to summarize the value in the "Amount" column for each record and display the summarize value in the footer of the "Amount" column.
I added some code to the "ItemTemplate" and "FooterTemplate" of the template for the "Amount" field and wrote two functions One function adds the value of the "Amount" field to a variable called "TotalAmount" and the second function 'gets' the value stored in the "TotalAmount" variable.
I am not getting any error messages and all of the items are displayed in the gridview but I am not displaying anything at the bottom of the "Amount" column. What more do I need to do?
This is my code for the "Amount" template:
<asp:TemplateField
HeaderText="Amount"
SortExpression="Amount">
<EditItemTemplate>
<asp:TextBox
ID="TextBox1"
runat="server"
Text='<%# Bind("Amount") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label
ID="Label1"
runat="server"
Text='<%# Bind("Amount", "{0:c}") %>'>
<%#SumAmount(Eval("Amount")) %></asp:Label>
</ItemTemplate>
<FooterTemplate>
<%#GetTotalAmount() %></FooterTemplate>
<FooterStyle
BorderColor="Black"
BorderStyle="Solid"
/>
</asp:TemplateField>
This is the code in my .vp file
Dim TotalAmount as decimal 0.0
Function SumAmount(ByVal Amount
As
Decimal)
As
Decimal
TotalAmount = TotalAmount + TotalAmount
End
Function
Function GetTotalAmount()
As
Decimal
Return TotalAmount
End
Function

to format the currency values and on my local machine everything works correctly displaying the currency in £ (pounds).
I moved my code onto the server that it will be run from and it's displaying in $ (dollars).
Our technical team that look after the server (Development aren't allowed access to the admin side of things) say that the server is set up for UK.
Where should they be looking to be able to set the server to display the data correctly?
